1. Safety Labeling and Signal Words

Danger, Warning and Caution

The signal words DANGER, WARNING and CAUTION are used to identify levels of hazard seriousness. The signal word DAN-

GER is only used on product labels to signify an immediate haz- ard. The signal words WARNING and CAUTION will be used on

product labels and throughout this manual and other manuals that may apply to the product.

2. Safe Installation Requirements

Installation or repairs made by unqualified persons can result

in hazards to you and others. Installation MUST conform with local building codes or, in the absence of local codes, with the

National Electrical Code NFPA70-1990 or current edition.

The information contained in this manual is intended for use by a qualified service technician familiar with safety proce-

dures and equipped with the proper tools and test instru- ments.

Failure to carefully read and follow all instructions in this

manual can result in unit malfunction, property damage, per- sonal injury and/or death.

• Seal supply and return air ducts.

• Check to see that filters are installed correctly and are the proper type and size.

NOTE: It is the personal responsibility and obligation of the cus-

tomer to contact aqualified installer to ensure that the installation

is adequate and conforms to governing codes and ordinances.

CAUTION

Do NOT operate unit in a corrosive atmosphere containing chlorine, fluorine, or any other corrosive chemicals.

3. Locating & Installing The Unit

The unit is designed for outdoor installation only. Place the unit on a platform at ground level. The unit may be installed on a concrete

slab of 48" (1219mm) x 48" (1219mm) dimensions. Cement blocks on a 3" sand footing will also work. The slab or blocks

SHOULD NOT be in contact with any part of the structure. Check local codes covering zoning, noise, platforms, etc..

If practical avoid locating next to fresh air intakes, vent or bed-

room windows. Noise may carry into the openings and disturb people inside.

Avoid installations under roof overhangs without guttering. Water draining from the roof onto the unit could produce excessive

noise, and may cause ice to build up on coil or fan.

Placement of the unit should be in a well drained area or the unit

MUST be supported high enough so runoff will not enter the unit.

Do not locate unit where heat, lint or exhaust fumes wil! be dis-

charged on unit (as from dryer vents.)

Clearances

Minimum clearances, as specified in FIGURE 1, MUST be main- tained from adjacent structures to provide adequate air circula-

tion and room for service personnel. While minimum clearances are acceptable for safety reasons,

they may not allow adequate air circulation around the unit for proper operation. Whenever possible, it is desirable to allow addi-

tional clearance, especially around the condenser inlet and dis- charge openings.

Do NOT install the unit in a recessed or confined area that will per-

mit discharged air from the condenser to recirculate to the con- denser inlet.

Dimensions

NOTE: DUCT COLLARS ATTACHED TO SUPPLY AND RETURN MUST BE REVERSED AT INSTALLATION. SEE INSTRUCTIONS ON PAGE 3.

Installation

CAUTION

The unit must be installed as level as possible, with a maxi- mam slope no greater than 1/8" per foot (lOmm per meter).

For side to side leveling, the condensate drain side of the

unit MUST always be lower to provide proper drainage.

The unit MUST be situated in such a way as to provide safe access for servicing.

The platform may be made of either concrete or pressure treated wood and MUST be level and strong enough to

support the unit's weight.

2. Make sure when pushing the collars into place that the "V" flange of the collars seats into the supply and return holes

securely.

3. Re-install screw in each collar so it goes through both of the

holes in the collar end. It does not matter how the ends of

the collar overlap in order to accomplish this.

FIGURE 3 I Duct Collar Installation

Position platform separate from the building's foundation.

Install in a well-drained area, with the top surface of the platform high enough above grade level to allow installa-

tion of a condensate drain trap. See FIGURE 4

426 01 1005 O0

Condensate Drain

The condensate drain outlet is a 3/4" (19.1 mm) threaded female

PVC connection located at the bottom of the unit to the left of the

evaporator access panel. The circulating blower and the condenser fan create a negative

pressure on the condensate drain line that will prevent the con- densate from draining properly without a trap. To combat this neg- ative pressure, a field supplied condensate trap that will allow a

standing column of water of at least 2" (50.8mm) MUST be

installed. The outlet of the trap must be at least 1" below the unit

drain connection. Install the trap as near to the unit as possible

for proper drainage.

A 3/4" (19.1 mm) drain line MUST be installed if required by local codes or iflocation of unit requires it. Run the drain line to an open

drain or other suitable disposal point.

4. Electrical Wiring

Electrical shock hazard.

Disconnect power at fuse box or service panel before

making any electrical connections.

Unit MUST be grounded to electrical service panel. Failure to follow this warning can result in property

damage, personal injury, and/or death.

NOTE: All electrical work MUST conform with the requirements of local codes and ordinances and in the United States with National

Electrical Code ANSI/NFPA 70-1990 (or current edition). Provide

line voltage power supply from a separate fused circuit with a dis- connect switch (when required) located within sight of the unit. Supply voltage, amperage, fuse and disconnect switch sizes

MUST conform with local codes and ordinances. Wiring MUST be protected from possible mechanical damage

and MUST NOT interfere with removal of access panels, filters,

etc.

All exposed line voltage connections MUST be made through liq- uid tight conduit to prevent water from entering the unit through

the electrical access..

Ground Connections

A ground lug is installed on the control plate (or electric heat mounting plate) for the ground connection. Use a copper conduc-

tor of the appropriate size from the unit to a grounded connection

in the electrical service panel or to a properly driven and electrical-

ly grounded ground rod.

Line Voltage Wiring

Do NOT complete line voltage connections until unit is perma- nently grounded. All line voltage connections and the ground con-

nection MUST be made with copper wire. Connections for line voltage are made on the unit electrical con-

trol plate (see FIGURE 7). For access, remove the Blower/Elec- trical access panel.

Refer to applicable wiring diagram and FIGURE 6. Complete the

line service connections to the contactor 'L' terminals on the elec-

A Disconnect Switch Kit is available that installs inside the unit or a seperate circuit breaker may be installed to control the unit. Re-

fer to instructions following heater installation section.

Converting 230V Units to 208V

To convert 230V units to 208V:

1. Turn electric power OFE

2. Remove the blower/electrical access panel.

3. Locate the 24V control transformer.

4. Remove wire from the terminal labeled "240V" on the 24V control transformer and reconnect it to the 208V terminal of the 24V control transformer.

5. Replace the electrical/compressor access panel.

Low Voltage Wiring

For access, remove the electrical control/blower access panel. Refer to the connection wiring diagram for the applicable model

and to the instructions included with the thermostat.

Route low voltage wires through the port located on the rear panel

and up to the control box. NOTE: If an Electric Heat Accessory is installed, see the Electric

Heat Accessory Installation Section of this manual for low voltage

connections.
